Description

Technical Field

[0001] The present invention relates to a conveying device for bulk solid materials, and particularly to a spherical four-way device. Background Art

[0002] In bulk material conveying systems such as chemical industry, metallurgy, grain, building materials, ports, power, coal, and mines, material diversion and transfer are often required. The traditional three-way device can achieve material diversion and transfer by switching the position of the turning flap. During the actual material transportation process, when a complex process requires the conversion of three processes, it is only possible to configure another three-way device downstream of one three-way device, that is, in a series connection of two three-way devices. Although this can meet the actual operation requirements, it also brings many problems. First, when using the series connection of two three-way devices, the height of the turret for material transportation increases, which may interfere with other buildings during actual installation and affect the normal operation effect. At the same time, the construction cost and operation cost are increased. Second, the series connection of two three-way devices increases the probability of funnel blockage. Third, the increase in the turret height easily causes too large an impact force of the material drop on the downstream belt, reducing the service life of the belt. Fourth, the traditional flap-type electric three-way device has problems such as the flap not being able to reach the position, the flap shaft breaking, the flap being worn through, clamping the material and getting stuck, and blocking the material during on-site use, seriously affecting the normal operation of the equipment, greatly reducing the reliability of the equipment, and seriously affecting the normal operation of the bulk material conveying system. Summary of the Invention

[0003] The object of the present invention is to provide a spherical four-way device to solve the problems existing when a complex process requires the conversion of three processes during the actual material transportation process, such as the need for a series connection of two three-way devices, the flap not being able to reach the position, the flap shaft breaking, the flap being worn through, clamping the material and getting stuck, and blocking the material.

[0004] To achieve the above object, the technical solution of the present invention is: A spherical four-way device includes a feed inlet, an axial bearing structure, an arc-shaped diversion pipe, a spherical shell, a first discharge port, a second discharge port, a third discharge port, a transmission shaft, an axial bearing, a motor support, and a servo motor. The spherical shell is in the middle. The feed inlet is arranged above the spherical shell, connected by a flange and fastened with bolts. The axial bearing structure is arranged above the inside of the spherical shell, connecting and supporting the arc-shaped diversion pipe. The transmission shaft is arranged below the arc-shaped diversion pipe and fixed on the axial bearing. The first discharge port, the second discharge port, and the third discharge port are arranged below the spherical shell, with the center line angles evenly distributed at 120°, and welded and fixed on the spherical shell. The servo motor is fixed on the motor support below the spherical shell.

[0005] A conical funnel is arranged inside the feed inlet, and wear-resistant materials such as wear-resistant ceramics or wear-resistant steel plates are laid on the inner surface.

[0006] The inner surfaces of the arc-shaped diversion pipe, the first discharge port, the second discharge port, and the third discharge port are lined with wear-resistant materials such as wear-resistant ceramics or wear-resistant steel plates.

[0007] The transmission shaft, the axial bearing, and the servo motor must be on the same axis as the axial bearing structure.

[0008] Advantages of the present invention Compared with the prior art, the present invention solves the problems existing in the actual material transportation process when three process conversions are required, such as the need for two three-way devices in series, the flap cannot be fully opened, the flap shaft breaks, the flap wears through, the material clamping gets stuck, and the material gets blocked. It changes the traditional flap type or swing cylinder type switching method into a switching method with a bearing rotation structure that has small friction and a reliable and stable structure. Through the convergence and diversion of the material flow at the feed inlet, the arc-shaped diversion pipe accurately and completely receives the material flow, allowing the material flow to slide out from the discharge port along the arc-shaped diversion pipe and enter the next-stage chute or downcomer, avoiding the problem of the material flow splashing and filling the movable gap between the baffle and the housing, which causes the baffle to get stuck; through the reasonable layout of the wear-resistant materials on the inner walls of the feed inlet, the arc-shaped diversion pipe, and the discharge port, the service life of the four-way device can be improved; axial bearings are provided above and below the arc-shaped diversion pipe, thus greatly reducing the power required for the arc-shaped diversion pipe to change direction.
